Vinyl RPM Rotations
See how many rotations a record makes for a given play time.
About Vinyl RPM Rotations
At a set speed the platter turns a fixed number of times per minute, so total rotations scale directly with play time. Knowing revolutions matters for groove spacing, stylus wear and why the same song runs longer at 33 than at 45.
Formula
Vinyl RPM Rotations
Rotations = RPM x minutes; seconds per rotation = 60 / RPM
- RPM
- Revolutions the platter makes per minute
Worked example
With the default values below, Vinyl RPM Rotations returns Total Rotations of 733.3. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits
- The result is derived only from the 2 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
- Figures are rounded for display to 3 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
